I got same problem in one of my VM, both via Windows Update and stand-alone update. It pass windows updating and when rebooting it failed at stage of around 74% finished and need to revert back. Check eventlog and I notice the error message for update comes almost immediately with an error for not be able to stop "Tile Data Model Server" service. So, I disable this service and try again. This time it pass the update. Just post in case it can help.
